The "How do I make a weapon do that?" thread

[Ivory]

Well get over it. Zdoom wiki is your best friend.

How would I go about making a shotgun weapon that returns a portion of the damage done as ammo?

[Russel]

As if it uses a projectile-based thing, it can use XDeath and A_GivetoTarget to give the ammo type

[Lighjing]

So I've gotten the regenerating ammo part finished, now how would I make the bullets it fire spread out in a random pattern?

[Russel]

A_FireCustomMissile("MissileName",random(number,-number),blah, blah,blah) just horizontal

Or add +WEAPON.NOAUTOAIM and
A_FireCustomMissile("MissileName",random(number,-number),blah, blah,blah,0,random(number,-number))
for random vertical aiming too

not related to weapons but whatever

Is it possible to have a player "die" (complete with the "killer" getting a message and earning a frag), but come "back to life" shortly after dying? This means that the revived player will retain any weapons / items / etc they had before dying. It's not a simple respawn or anything.

Also, is it possible for a weapon to take a frag AWAY from its victim upon a successful kill?

Try these for the first thing.
I make no promises.

As for taking frags away, you could have the victim kill itself through a pain state.
Not going to question why you would actually want this of course.

Not that I'm working on any weapon coding, but...

Is it possible to make a weapon that acts like a 3D version of Radd Spencer's bionic arm? A weapon that sticks to any surface and allows the user to make very long jumps by attaching it to the ceiling and swing to the other side. Said swing would have a constant velocity and no decay, for accuracy purposes... I just want to know if it's possible, and where could someone start to work on it, if someone where to do so.

Lego's MM8-10 pack's ThunderClawWep.

Not technicly a weapons but works like one

How do I make a infinite use item? Like say, use the item and you fire a shot, but the item stays and can be reused?

[Gummywormz]

At the end of the sequence put the word "fail" (without quotes). Or just give the same item at the end of the sequence.

Invulnerability. *sigh*

I have no idea how Skulltag invulnerability works, but I want to make an effect where a player is immune to all forms of damage like Skull Barrier. God Mode doesn't protect you from certain things like Quick Beams or Gamma's fireball attack, but Skull Barrier DOES.

However, I also want the player to die from falling in a pit somewhere (you know, the whole "fell too far" schtick). IIRC both Skull Barrier AND God Mode prevent you from dying in pits, which is problematic since I want the "good" invuln from Skull.

I'm aware that this is probably very difficult (if not impossible) to do, but if you have ANY ideas AT ALL how I can accomplish such a feat, I'm all ears.

[Korby]

My suggestion is to stare at Skull Barrier and Beat's coding.

If you use the "beat way" of activating something, you could deactivate your shield when you fall in a pit.

[Hallan Parva]

I thought the Beat Call script was only on certain maps. Correct me if I'm wrong, but wouldn't certain stages therefore be unable to take the invulnerability away from you (as they lack Beat Call checkers in their pits)?

[Korby]

Probably
